Las Vegas Aces vs. Toronto Tempo

Platform comparison

Market context

The Las Vegas Aces face the Toronto Tempo in a WNBA regular-season contest at Coca-Cola Coliseum in Toronto, scheduled for 8:00 p.m. ET on Monday, 20 July 2026. Sportsbooks heavily favour the Aces as a –11.5 road team with a –575 moneyline, implying roughly 85 % win probability, while prediction markets show a stark divergence by pricing the Aces at 100 % YES[1][3]. Analysts uniformly project a 99–88 Aces victory, reinforcing the sportsbook line but leaving the prediction-market certainty unexplained by traditional odds models[2][6].

Historically, 100 % implied probabilities in single-game sports contracts are rare and usually signal either a suspended market, a known outcome, or a pricing error. Comparable cases—such as pre-injury collapses in NBA games or postponed fixtures that never resolved—show that such extremes often correct once live data arrives or if the event is delayed. The current 100 % figure contrasts sharply with the 78.9 % implied probability derived from the Aces’ superior 78.60 CPI rating versus Toronto’s 15.07, suggesting the market may be overconfident or misaligned with underlying performance metrics[8].

Traders should monitor the final roster announcements for the Aces, particularly whether star A’ja Wilson plays the second game of a back-to-back, and any in-game injury reports that could shift momentum. The over/under line of 182.5 points is another key dependency; if the game stays under, the Aces’ defensive dominance may still secure the win even without a cover[1][2]. NBCSN and Peacock will broadcast the match, with play-by-play by Zora Stephenson and analysis by Sarah Kustok, offering real-time data for live trading adjustments[5].

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
